Now that your rotary encoder hardware is up and running it’s time to tell your Arduino what to do with the encoder signals ... With polling you read the input all the time inside a loop. With ...

trapping itself in a never-ending loop. [Mirko] solved this by encasing the Arduino inside a closed, grounded metal box with only the required wires sticking out. The antenna’s design was ...

The Arduino Wire library is a core aspect of Arduino's integrated development environment, or IDE, and is a must-have if you're using sensors or extra microcontrollers in your project. Like ...

it would be impossible to tell the difference between a legitimate lower limit reading on a sensor and a broken loop wire. So how do you incorporate a 4-20 mA device into your latest Arduino ...

wire, a cardboard box, and an Arduino microprocessor to crunch the numbers. That’s it. It couldn’t be more simple. But how’d he pull it off? The rig uses simple RC circuits to sense the ...
